hashlib,logging,traceback模块

用md5进行进行加密,为了防止撞库,所以一定要加盐,因为加密后不可以反解,因此进行校对时可以使用密文进行,还需注意的是md5加密的是字节,所以需要用encode进行编码

加密实例

import hashlib

salt = b"asdfghjkl;ei"


def func(pwd):
    # 实例化对象
    obj = hashlib.md5(salt)
    # 写入加密字节
    obj.update(pwd.encode("utf-8"))
    # 获取密文
    return obj.hexdigest()


name = input(">>>")
pwd = input(">>>")
if name == "123" and func(pwd) == "fb5e8b7ebcd71d0ac0ecf803ff8aba74":
    print("登陆成功")

日志文件

logger = logging.basicConfig(filename=‘xxxxxxx.txt‘,
                             format=‘%(asctime)s - %(name)s - (levelname)s -%(module)s:  %(message)s‘,
                             datefmt=‘%Y-%m-%d %H:%M:%S‘,
                             level=30)
# 参数设置
# 等级
# logging.debug(‘x1‘) # 10
# logging.info(‘x2‘)  # 20
# logging.warning(‘x3‘) # 30
# logging.error(‘x4‘)    # 40
# logging.critical(‘x5‘) # 50
# logging.log(10,‘x6‘)

# 自定义日志
logging.error(‘x4‘)

将日志写入一个文件中

import logging
import traceback
logger = logging.basicConfig(filename=‘xxxxxxx.txt‘,
                             format=‘%(asctime)s - %(name)s - %(levelname)s -%(module)s:  %(message)s‘,
                             datefmt=‘%Y-%m-%d %H:%M:%S‘,
                             level=30)


def func():
    try:
        a = a +1
    except Exception as e:
        # 获取当前错误的堆栈信息
        msg = traceback.format_exc()
        logging.error(msg)
func()

将日志写入多个文件中

import logging


# 创建一个操作日志的对象logger（依赖FileHandler）
file_handler = logging.FileHandler(‘log1.log‘, ‘a‘, encoding=‘utf-8‘)
file_handler.setFormatter(logging.Formatter(fmt="%(asctime)s - %(name)s - %(levelname)s -%(module)s:  %(message)s"))

logger1 = logging.Logger(‘s1‘, level=logging.ERROR)
logger1.addHandler(file_handler)


logger1.error(‘1‘)



# 在创建一个操作日志的对象logger（依赖FileHandler）
file_handler2 = logging.FileHandler(‘log2.log‘, ‘a‘, encoding=‘utf-8‘)
file_handler2.setFormatter(logging.Formatter(fmt="%(asctime)s - %(name)s - %(levelname)s -%(module)s:  %(message)s"))

logger2 = logging.Logger(‘s2‘, level=logging.ERROR)
logger2.addHandler(file_handler2)

logger2.error(‘2‘)
